DETAILED DESCRIPTION

[0049] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0050] like Figure 1-Figure 18 As shown, some embodiments of the present application provide an air guide plate, an air conditioner indoor unit and an air conditioner.

[0051] like Figure 1-Figure 5 As shown, the wind deflector 100 provided in one embodiment of the present application comprises an inner wind deflector 1 and an outer wind deflector 2 which are fixedly connected, a mounting cavity 3 is formed between the inner wind deflector 1 and the outer wind deflector 2, a side wall of the inner wind deflector 1 which faces away from the mounting cavity 3 forms an airflow guiding surface, and the outer wind deflector 2 is located on the leeward side of the inner wind deflector 1. A mounting base 21 for rotatably mounting the wind guide blade 4 is provided on a side wall of the outer wind deflector 2 which faces the mounting cavity 3, and a through hole 11 for the wind guide blade 4 to pass through is provided on the inner wind deflector 1.

[0052] The air guide plate 100 of the embodiment of the present application is installed at the air outlet position of the indoor unit of the air conditioner, and the hot air or cold air blown out of the indoor unit of the air conditioner can be blown into the room through the air outlet. The air guide plate 100 of the embodiment of the present application forms an airflow guiding surface on the side of the inner air guide plate 1 away from the installation cavity 3, and the airflow guiding surface of the air guide plate 100 can be used to guide the flow direction of the airflow blown out from the air outlet of the indoor unit of the air conditioner. The installation base 21 of the outer air guide plate 2 is installed with an air guide blade (such as a shutter form) 4 that can rotate to a certain angle (i.e. swing), and the indoor unit of the air conditioner is also provided with a driving mechanism for driving the air guide blade 4 to swing. Through the swinging movement of the air guide blade 4, the airflow blown out from the air outlet flows toward all directions of the room, thereby increasing the blowing range of the indoor unit of the air conditioner and improving the cooling or heating effect of the indoor unit of the air conditioner.

[0053] The wind guide plate 100 of the embodiment of the present application is provided with an inner wind guide plate 1 and an outer wind guide plate 2 fixedly connected. The wind guide plate 100 is a two-layer structure with high strength, so that the wind guide plate 100 is not easily deformed and damaged by external vibration (such as: the swing of the wind guide blade 4 drives the wind guide plate 100 to vibrate and be damaged, and the deformation of the wind guide plate 100 caused by the high temperature and low temperature airflow blown out of the air outlet can be improved. Figure 5 As shown, a side wall of the outer air guide plate 2 facing the mounting cavity 3 is provided with a mounting base 21 for rotatably mounting the air guide blade 4, and the inner air guide plate 1 is provided with a through hole 11 for the air guide blade 4 to pass through, so that the air guide blade 4 passes through the through hole 11 of the inner air guide plate 1 and is connected to the mounting base 21 on the outer air guide plate 2, so as to realize the rotational connection between the air guide blade 4 and the air guide plate 100. Due to the enhanced strength of the air guide plate 100, the rotational movement of the air guide blade 4 itself will not cause a large vibration of the air guide plate 100, and the rotational movement of the air guide blade 4 has little effect on the deformation of the air guide plate 100. Therefore, the air guide plate 100 of the embodiment of the present application has good anti-deformation performance.

[0054] Compared to installing the air guide blade 4 to the inner air guide plate 1, installing the air guide blade 4 to the mounting base 21 arranged in the mounting cavity 3 of the air guide plate 100 allows a portion of the air guide blade 4 to extend into the mounting cavity 3 of the air guide plate 100, which is beneficial to reducing the size of the portion of the air guide blade 4 located outside the air guide plate 100, and further beneficial to reducing the overall size of the air conditioner indoor unit.

[0055] In addition, in the existing wind deflector, a connection structure connected to the chassis is designed in the middle of the wind deflector to enhance the anti-deformation ability of the wind deflector, resulting in a bent portion in the middle of the connecting rod connecting the wind guide blades to avoid the connection structure in the middle of the wind deflector. The wind deflector 100 of the embodiment of the present application has high structural strength and strong anti-deformation ability, so the connection structure connecting the middle of the wind deflector 100 with the chassis can be eliminated, so that the connecting rod 6 connecting the wind guide blade 4 no longer needs to be designed with a middle bent portion, so that the connecting rod 6 can be in a straight line, and after the connecting rod 6 is straightened, an additional wind guide blade 4 can be set in the middle position to increase the wind sweeping range.

[0056] In an exemplary embodiment, Figure 4 , Figure 5 and Figure 7 As shown, a mounting hole 211 is provided on one end surface of the mounting base 21 facing the inner air guide plate 1 , a bayonet 212 is provided on the side wall surface of the mounting base 21 , and the bayonet 212 extends radially inwardly along the mounting hole 211 until it is connected to the mounting hole 211 .

[0057] The mounting base 21 is configured to allow the first hook 41 of the air guide blade 4 to extend into the mounting hole 211 and be slidably engaged with the bayonet 212 , so that the air guide blade 4 can rotate around the axis of the mounting hole 211 .

[0058] Specifically, the mounting base 21 is provided with a mounting hole 211 and a bayonet 212, so that the wind guide blade 4 can be smoothly mounted on the mounting base 21. Figure 4 and Figure 7 As shown, the bayonet 212 is configured to extend radially inwardly along the mounting hole 211 to communicate with the mounting hole 211, so that the first hook 41 of the air guide blade 4 can be snapped into the buckle 212 after passing through the mounting hole 211; the bayonet 212 can also make room for the rotational movement of the air guide blade 4, so that the air guide blade 4 can rotate to a certain angle.

[0059] The embodiment of the present application adopts a connection structure in which the first hook 41 is clamped to the clamping hole 212 of the mounting base 21 , which has a simple structural design and is easy to install and disassemble.

[0060] In an exemplary embodiment, a plurality of bayonet holes 212 are disposed on the side wall surface of the mounting base 21 , and the plurality of bayonet holes 212 are sequentially arranged along the circumference of the mounting hole 211 .

[0061] Specifically, a plurality of snap-in slots 212 are provided on the side wall surface of the mounting base 21, and a plurality of first hooks 41 can be provided on one end of the air guide blade 4, so that the plurality of first hooks 41 can be slidably engaged with the plurality of snap-in slots 212 in a one-to-one correspondence, making the connection between the air guide blade 4 and the air guide plate 100 more secure.

[0062] Optionally, two opposite bayonet holes 212 may be provided on the side wall surface of the mounting base 21 , so that the mounting base 21 has a simple structural design and is easy to process and assemble.

[0063] In an exemplary embodiment, Figure 4 , Figure 5 and Figure 7 As shown, a first supporting rib 22 is provided on one side wall of the outer air guide plate 2 facing the mounting cavity 3, a side surface of the first supporting rib 22 is connected to the mounting base 21, and an end surface of the first supporting rib 22 abuts against a side wall of the inner air guide plate 1 facing the mounting cavity 3. For example, the mounting base 21 can be connected to two first supporting ribs 22, and the two first supporting ribs 22 and the two bayonet holes 212 can be alternately arranged in sequence along the circumference of the mounting base 21.

[0064] Specifically, a first supporting rib 22 is provided between the outer air guide plate 2 and the inner air guide plate 1 to improve the overall structural strength of the air guide plate 100, so that the high-temperature and low-temperature airflows flowing through the air guide plate 100 will not easily cause a large deformation of the air guide plate 100, and the swinging movement of the air guide blades 4 will not force the air guide plate 100 to vibrate and deform significantly.

[0065] In addition, the first supporting rib 22 is connected to the mounting base 21, which can enhance the connection strength between the mounting base 21 and the outer air guide plate 2, thereby facilitating the installation stability of the air guide blade 4. Of course, the first supporting rib 22 can also be configured not to be connected to the mounting base 21.

[0066] In another exemplary embodiment, a second supporting rib is provided on a wall surface of the inner air guide plate 1 facing the installation cavity 3 , and an end surface of the second supporting rib abuts against a wall surface of the outer air guide plate 2 facing the installation cavity 3 .

[0067] Specifically, a second supporting rib is provided between the outer air guide plate 2 and the inner air guide plate 1 , which can also improve the overall structural strength of the air guide plate 100 and prevent the air guide plate 100 from being significantly deformed or damaged.

[0068] In an exemplary embodiment, Fig.11 As shown, a hollow structure 12 is provided in the inner air guide plate 1 .

[0069] Specifically, the inner air guide plate 1 can be formed by extrusion, and the inner air guide plate 1 is set as a hollow structure 12, so that the outer air guide plate 2 is not easy to deform under the support of the hollow structure 12 of the inner air guide plate 1. The structural design cost is low, the structure is simple, and a relatively low-cost design is used to achieve a better effect of preventing the air guide plate 100 from deforming.

[0070] In an exemplary embodiment, Figure 13-Figure 18As shown, a reinforcement member 5 is provided in the installation cavity 3 , one side wall of the reinforcement member 5 abuts against the side wall of the outer air guide plate 2 facing the installation cavity 3 , and the other side wall of the reinforcement member 5 abuts against the side wall of the inner air guide plate 1 facing the installation cavity 3 .

[0071] Specifically, a reinforcement member 5 is arranged in the installation cavity 3, and one side wall of the reinforcement member 5 is arranged to abut against the side wall of the outer air guide plate 2 facing the installation cavity 3, and the other side wall of the reinforcement member 5 is arranged to abut against the side wall of the inner air guide plate 1 facing the installation cavity 3. In this way, the overall structural strength of the air guide plate 100 composed of the inner air guide plate 1 and the outer air guide plate 2 is improved by the reinforcement rib 5, thereby preventing the air guide plate 100 from being deformed due to the forced vibration of the air guide blades 4 and the temperature change of the external airflow.

[0072] In an exemplary embodiment, the reinforcement member 5 is provided with one and is disposed at one end of the mounting cavity 3; or Fig.14 As shown, two reinforcement members 5 are provided and are respectively arranged at two opposite ends of the installation cavity 3 .

[0073] Specifically, the reinforcement member 5 is arranged at the end of the installation cavity 3 so as to support the space of the installation cavity 3 from the end of the installation cavity 3 and improve the overall structural strength of the wind deflector 100. The reinforcement member 5 is arranged at the end of the installation cavity 3 to leave enough space for the installation base 21 and the first hook 41 to prevent the reinforcement member 5 from interfering with the normal and smooth rotation of the wind guide blade 4. One or two reinforcement members 5 may be provided; the two reinforcement members 5 may be the same, or different as needed.

[0074] In an exemplary embodiment, Fig.14 and Fig.16 As shown, at least one of the side wall of the outer air guide plate 2 facing the installation cavity 3 and the side wall of the inner air guide plate 1 facing the installation cavity 3 is provided with a first buckle 23, and the reinforcement 5 is provided with a first buckle portion 51, which is snap-fitted with the first buckle 23.

[0075] Specifically, the first buckle 23 and the first buckling portion 51 are engaged with each other to fix the connection position of the reinforcement member 5 in the installation cavity 3, and the reinforcement member 5 is firmly connected in the installation cavity 3, thereby preventing the reinforcement member 5 from shaking in the installation cavity 3 of the air guide plate 100. In addition, the engagement structure has a simple structural design and is easy to process and assemble.

[0076] In an exemplary embodiment, Fig.14 and Fig.15 As shown, at least one of the side wall of the outer air guide plate 2 facing the installation cavity 3 and the side wall of the inner air guide plate 1 facing the installation cavity 3 is provided with a limiting rib 13, and the limiting rib 13 cooperates with the reinforcement 5 to limit the position.

[0077] Specifically, the limiting retaining rib 13 limits the reinforcement member 5 at the end of the installation cavity 3, so that the reinforcement member 5 at the end of the installation cavity 3 can better support the space of the installation cavity 3. The limiting retaining rib 13 limits the reinforcement member 5 at the end of the installation cavity 3, and can also prevent the reinforcement member 5 from shaking in the installation cavity 3 to the vicinity of the installation base 21 and the first buckle 41, thereby interfering with the normal rotation of the wind guide blade 4.

[0078] In an exemplary embodiment, Figure 14-18 As shown, the reinforcement 5 includes a first reinforcement plate 52, a second reinforcement plate 53 and a connecting rib 54. The first reinforcement plate 52 and the second reinforcement plate 53 are arranged opposite to each other. The connecting rib 54 is located between the first reinforcement plate 52 and the second reinforcement plate 53, and the two ends of the connecting rib 54 are respectively connected to the first reinforcement plate 52 and the second reinforcement plate 53.

[0079] The side wall of the first reinforcing plate 52 facing away from the second reinforcing plate 53 abuts against the side wall of the outer air guide plate 2 facing the installation cavity 3 , and the side wall of the second reinforcing plate 53 facing away from the first reinforcing plate 52 abuts against the side wall of the inner air guide plate 1 facing the installation cavity 3 .

[0080] Specifically, the reinforcement 5 adopts a roughly I-shaped structure composed of a first reinforcement plate 52, a second reinforcement plate 53 and a connecting rib 54, which can improve the overall structural strength of the reinforcement 5 and reduce the weight of the reinforcement 5, so that the overall mass of the air guide plate 100 is lighter and has a strong deformation resistance.

[0081] In an exemplary embodiment, Fig.14 , Fig.15 and Fig.16 As shown, along the direction pointing to the center of the installation cavity 3, the distance between the first reinforcing plate 52 and the second reinforcing plate 53 gradually increases.

[0082] Specifically, the spacing between the first reinforcing plate 52 and the second reinforcing plate 53 is set along the direction pointing to the center of the installation cavity 3 (such as the bottom-up direction in 15 or the Fig.16 The shape of the reinforcement 5 is adapted to the shape of the end of the installation cavity 3, so that the reinforcement 5 can better support the installation cavity 3 space of the air guide plate 100, and avoid the frequent and long-term rotation movement of the air guide blades 4 causing the air guide plate 100 to be deformed due to forced vibration, thereby causing displacement and deformation of both the inner air guide plate 1 and the outer air guide plate 2.

[0083] In an exemplary embodiment, Fig.15 and Fig.17 As shown, a plurality of connecting ribs 54 are provided, and the plurality of connecting ribs 54 are arranged in sequence, and a cavity is formed between two adjacent connecting ribs 54 .

[0084] Specifically, a plurality of connecting ribs 54 are provided, and a cavity is formed between two adjacent connecting ribs 54, so as to improve the structural strength of the reinforcement 5, so that the air guide plate 100 has a stronger anti-deformation ability and a lighter weight.

[0085] In an exemplary embodiment, Figure 4 and Figure 5 As shown, a second buckle 24 is provided at the end of the outer air guide plate 2 , and a second buckle 14 is provided at the end of the inner air guide plate 1 , and the second buckle 14 is snap-fitted with the second buckle 24 .

[0086] Specifically, both ends of the outer air guide plate 2 may be provided with a second buckle 24, and both ends of the inner air guide plate 1 may be provided with a second buckle 14, and the two second buckle 14 may be respectively engaged with the two second buckles 24 to engage and fix the outer air guide plate 2 and the inner air guide plate 1, which is convenient for assembly and disassembly between the outer air guide plate 2 and the inner air guide plate 1, and is helpful for operators to maintain the air guide blades 4 and the air guide plate 100. In addition, the connection structure is simple in design and easy to manufacture.

[0087] In an exemplary embodiment, the mounting base 21 is integrally formed with the outer air guide plate 2 .

[0088] Specifically, the mounting base 21 is integrally formed with the outer air guide plate 2, and the mounting base 21 can be integrally formed with the outer air guide plate 2 by using an injection molding process, thereby improving the connection strength between the mounting base 21 and the outer air guide plate 2, and preventing the mounting base 21 and the air guide blades 4 from being displaced and deformed relative to the air guide plate 100. The mounting base 21 is integrally formed with the outer air guide plate 2, which also simplifies the processing technology and improves the efficiency of producing the air guide plate 100.

[0089] In an exemplary embodiment, the outer air guide plate 2 is a plastic member, and the inner air guide plate 1 is a metal plate.

[0090] Specifically, the inner air guide plate 1 is made of a metal plate, such as an aluminum plate or other materials, which can ensure that the air guide plate 100 has a relatively high strength; the outer air guide plate 2 is made of a plastic member, and the density of the plastic material is relatively low, so that the overall mass of the outer air guide plate 2 and the air guide plate 100 is relatively light. Of course, the materials of the outer air guide plate 2 and the inner air guide plate 1 are not limited to the above, and can also be adjusted as needed.

[0091] In an exemplary embodiment, Fig.12 As shown, the outer air guide plate 2 and the inner air guide plate 1 are an integrated structure.

[0092] Specifically, the outer air guide plate 2 and the inner air guide plate 1 are configured as an integrated structure, that is, the air guide plate 100 as a whole is an integrated structure, which can simplify the manufacturing process and assembly process of the air guide plate 100 .

[0093] In an exemplary embodiment, the outer air guide plate 2 and the inner air guide plate 1 are an integrated structure formed by gas-assisted injection molding.

[0094] Specifically, the process of gas-assisted injection molding is: injecting high-pressure nitrogen directly into the plasticized plastic in the mold cavity through a segmented pressure control system, so that the inside of the plastic part expands and becomes hollow, but still keeps the surface appearance of the product intact. The air guide plate 100 is set as an integrated structure, and the air guide plate 100 is manufactured by gas-assisted injection molding, so that the air guide plate 100 of the embodiment of the present application has the advantages of gas-assisted injection molding: saving raw materials for manufacturing the air guide plate 100 and reducing material costs; shortening the molding cycle for manufacturing the air guide plate 100 and reducing production costs; simplifying the complicated design of the product and reducing manufacturing costs. The integrated structure of gas-assisted injection molding can eliminate the need for spraying the air guide plate 100, and the appearance requirements can be met.

[0095] In addition, the air guide plate 100 is set as an integrated structure. Compared with the ordinary injection molding process, the air guide plate 100 is manufactured by gas-assisted injection molding process, which can reduce the mold cavity pressure, extend the service life of the mold, eliminate shrinkage marks, reduce the distortion and deformation of the overall structure of the air guide plate 100, and improve product quality.

[0096] In an exemplary embodiment, the material of the outer air guide plate 2 and / or the inner air guide plate 1 is PC+GF10.

[0097] Specifically, PC+GF10 is a reinforced PC (Polycarbonate) plastic containing 10% glass fiber. PC+GF10 material has the advantages of good dimensional stability, strong impact resistance, heat resistance and flame retardancy, and PC+GF10 has good mechanical processing performance. The experimenters of this application verified through single-body wet heat and high and low temperature tests that: compared with the outer air guide plate 2 and the inner air guide plate 1 set as ABS material, the outer air guide plate 2 and the inner air guide plate 1 are set as PC+GF10 material, and the deformation of the air guide plate 100 is smaller.

[0098] The experimenters of this application conducted the following experiments:

[0099] Low temperature experiment - Place the air guide plate 100 horizontally, with the inner air guide plate 1 facing upwards, and support the two ends of the air guide plate 100 with fulcrums. The fulcrum positions are Figure 1 The circular holes at both ends of the air guide plate 100 are hooked to make the middle part of the air guide plate 100 suspended in the air. The experimental environment temperature is -40°C, the experimental time is 7 days, and the deformation of the air guide plate 100 is measured every week.

[0100] High temperature experiment - Place the air guide plate 100 horizontally, with the inner air guide plate 1 facing upwards, and support the two ends of the air guide plate 100 with fulcrums. The fulcrum positions are Figure 1The circular holes at both ends of the air guide plate 100 are hooked to make the middle part of the air guide plate 100 suspended in the air. The experimental environment temperature is 70° C., the experimental time is 7 days, and the deformation of the air guide plate 100 is measured every week.

[0101] Wet heat test - Place the air guide plate 100 horizontally, with the inner air guide plate 1 facing upwards, and support the two ends of the air guide plate 100 with fulcrums. The fulcrum positions are Figure 1 The circular holes at both ends of the air guide plate 100 are hooked to make the middle part of the air guide plate 100 suspended in the air. The experimental environment temperature is 70° C., the humidity is 85%, the experimental time is 7 days, and the deformation of the air guide plate 100 is measured every week.

[0102] For the three types of air guide plates, namely, the air guide plate 100 made of ABS material, the air guide plate 100 made of ABS material and the installation cavity 3 is provided with a reinforcement 5, and the air guide plate 100 made of PC+GF10 material, at the upper air outlet (upper edge) of the air guide plate 100 (such as Fig.19 The three positions A1, A2, and A3 shown in the figure) and the three points of the downwind outlet (such as Fig.19 The deformation is measured at the three positions (B1, B2, and B3) shown in the figure. The deformation unit is mm. The experimental results are shown in Tables 1-2 and Figure 20-21 shown.

[0106]

[0107] (“Original data” refers to the data tested after the air guide plate is produced, and the data before the experiment is carried out)

[0108] From the above Table 1 and Fig. 20 It can be seen from the experimental data that the deformation of the wind guide plate 100 made of ABS material and provided with a reinforcement 5 in the installation cavity 3 of the wind guide plate 100 is smaller at the same position of the upper air outlet and the lower air outlet than the wind guide plate 100 which only uses ABS material but does not have the reinforcement 5 in the installation cavity 3. Therefore, providing the reinforcement 5 in the installation cavity 3 of the wind guide plate 100 has the effect of enhancing the overall strength of the wind guide plate 100 and improving the deformation resistance of the wind guide plate 100.

[0109] From the above Tables 1-2 and Figure 20-21The experimental data show that the air deflector 100 made of PC+GF10 material has a smaller deformation at the same position of the upper and lower air outlets than the air deflector 100 made of ABS material and provided with a reinforcement 5 in the installation cavity 3, and the air deflector 100 made of PC+GF10 material has a stronger anti-deformation ability. The air deflector 100 made of PC+GF10 material has very small deformation at the upper and lower air outlets in high and low temperature and hot and humid environments, and the overall deformation is controlled within 1mm. Its single body experimental data is much better than that of the air deflector made of ABS material, and the deformation control is relatively ideal.

Therefore, the middle position of the connecting rod 6 does not need to be designed with a curved portion to avoid the connection structure between the air guide plate 100 and the chassis, so that the connecting rod 6 can be designed to be straight, thereby simplifying the structure of the connecting rod 6. After the connecting rod 6 is straightened, an air guide blade 4 can be added to the middle position thereof, thereby increasing the wind sweeping range of the air guide blade 4.
